PRESS.

SPECIFICATION forming part of Letters Patent No. 335,816, dated February9. 1886.

Application filed May 7, 1885.

To all whom, it may concern:

Be it known that I, JUL-iUs H. HOLMGREEN, of San Antonio, in the countyof Bexar and State of Texas, have invented a new and Improved Press, ofwhich the following is a full, clear, and exact description.

The object of my invention is to facilitate the baling of cotton andother fibrous substances.

The invention consists in compressing-rollers placed in suitablebearings, so as to coincide with an inlet-channel which receives andguides the fibrous substance to be baled into the baling-box of a pressafter the compressing-rollers have given it a preparatory press mg.

The invention further consists in details and combinations of parts, aswill hereinafter be fully described and claimed.

Figure 1 is a sectional view through the lines a: w of Fig. 2. Fig. 2 isan end View of the press, and Fig. 3 is a detail crosssectional view ofthe compressing-rollers.

In the drawings, A represents the balingbox of the press, which restsupon the supporting-timbers A, which are in turn supported by theground-timbers A The upper timbers, B, which rest upon the shoulder B ofthe tie-bolt B are parallel with the timbers A. The tie-bolts 13* unitethe upper and lower timbers, thereby making a firm and strong frame-workfor holding the different parts of the press in position.

The baling-box A has its side walls hinged at their bottoms to battens aon the timbers A, to facilitate the removal of the baled material afterbeing properly strapped. The baling-straps used for this purpose areheld in the spaces intervening between the floorslats a of the box A andthe slats a on the follower B. To the follower B, which works in thebaling-box A, is secured, by means of the bolt 0, the piston 0, workingin the hydraulic cylinder D. The cylinder has lugs e, which are securedto the cross-timbers b b by the bolts 6, thereby holding thecylinderfirmly in position. At the top of cylinder D a pressure-gage, E,is attached, and leading from the top of cylinder D to the water-tank G,which is held in position by the side projection, being secured to thetimbers B, is the exhaust Serial No. $4,667. (Nomodch) pipe F, havingsuitable stopcock, 'H, for exhausting the water in the hydrauliccylinder D when it is desired to raise the follower B. The pipe .T,which connects the pump I with the cylinder D, has a branch pipe, j,which leads to the tank for supplying the water for operating the pistonO.

The eccentric-rod i, which reciprocates the piston-rod 'i" of the pumpI, through the medium of the eccentric K on the shaft L, playshorizontally in the guide i, which projects downward from the bar I)" onthe timbers B. This holds the rod i against lateral movement. Theforward stroke of the pump-piston draws the water from the tank Gthrough the pipe j into the pipe J, and the return-stroke of thepump-rod closes the valve d, ope1 is valve d, and forces the waterthrough the pipe J into the cylinder D, where it acts on the piston O,causing the follower B to descend within the baling-box A. The eccentricK on the shaft L, which reciprocates the pump-piston i", receives itsmotion from pinion N which is loosely mounted on the shaft 0, meshingwith the gear-wheel N on the shaft L. To the outer end of the shaft 0the driving-pulley P is se; cured, and on the shaft 0 a gear-wheel, Q,is loosely mounted,which meshes with the gearwheel g on the roller S,and the pinion s on the opposite end of roller S revolves the roller Rby meshing with its pinion 1'. this train of gearing motion iscommunicated to the pump and compressing-rollers S and 1t, and as it isnecessary to work the compressingrollers R and S first independently ofthe pump a double clutch, p, is feathered on the shaft 0 between thegears N and Q. The clutch p is shifted to engage with clutches formed onthe opposite faces of the pinions N and Q by means of a forked lcverworking in the annular groove 1).

The compressing-rollers R and S are journaled in adjustable hearings toin the boX T, which are adjusted and held down by the springs u. Theside of the box T joining the feeding-apron WV is open, and on theopposite side of the box T a guiding inlet-channel, t, having its innerend beveled to fit against the rollers, is situated, the object of whichis to receive the material to be baled from the preparatory rollers Rand S and deliver it to the'baling-box A. It also prevents the mate rialfrom winding around the rollers R and S. In operating the press the pumpis thrown out of action by shifting the clutch p to engage with the gearQ and to be out of engagement with the pinion N. The pinion N, by beingloosely mounted on the shaft 0, receives no motion from said shaft, andconsequently the pump is at rest. The gear Q being engaged with thefeathered clutch pis caused to revolve, and by meshing with the pinionqthe motion is imparted to the roller S, and through pinions s and r tothe roller R. The material to be baled is now fed down the apron W tothe rollers R and S, between which it receives a preparatorycompressing, and then is forced by the said rollers into and through theinletchannel it to the baling-box. When the desired quantity has beenfed to the baling-box, the clutch p is shifted, which stops the rollersR and S and operates the pump I by the motion imparted to the eccentricK by the gears N and N. The pump I drawing water from the tank G andforcing it into the cylinderD, as before described, causes the followerB to descend withinthe baling-box A, and gives the material the finalpacking in the baling-box, after which the side walls are swung down andthe baling-straps adjusted, when the bale is removed.

Although I have here shown a hydraulic press, it is evident that thepreparatory compressing-rollers R and S may be used in connection withany form of press wit-h great advantages,as by the use of the rollersRand S the large unwieldy press-box now in common use is discarded and asmaller and more easilyman'aged one substituted, taking up less roomsubstantially as and for the purpose set forth.

and follower B, of the gear-wheels N N, the clutch p, the gear-wheels Qq, and the compressing-rollers R and S, substantially as herein shownand described.
